russman I don't know about other places, but did my first longer trip and used a few superchargers. Tejon, Harris, and Gilroy. All 3 had over 50% spaces filled and two of them were 100% or more filled at some point I was charging. Did get to see a P85D, but also noticed that most of the people there charging had no understanding. One person couldn't disconnect the cable, because his car was locked. No one I spoke to understood that the chargers were paired. It's only going to get worse... At Harris, someone had to wait for a spot to open up. Unfortunately, there were at least 3 cars that were there before I got there and after I left. The one good news was that none of the spots were iced.
Just some observations.�

randompersonx Most people are never going to understand things like pairing.
Not understanding how to disconnect the cable because the car is locked ... Don't they run into that at home?�
Dec 28, 2014
omarsultan Yeah, that's getting into "inside baseball" territory. It does not help that they don't seem to use a consistent scheme for placement of A and B chargers.�
Dec 28, 2014
Vger California is the only place I have seen saturated or nearly saturated SC's, but clearly, capacity will need to continue to got up.
I have also found most owners I have met at superchargers ignorant on the pairing. I have explained it patiently to many!
The one fun exception was at Truckee last week on my Gigafactory pilgrimage. I inadvertently started to pull into the paired spot of a car already charging. Before I even got my car parked, a young girl (about 12) bounded out of the other car and pointed out that I was about to slow down their charge. She was sitting reading alone in the car, while her Mom was shopping, and clearly keeping a sharp eye out-- kids these days! :wink:
I immediately apologized and moved to the adjacent slot. In the dark, I had trouble reading the labels.�
Dec 28, 2014
EarlyAdopter I thought the pairing meant your charge would be slow until their car starts to taper, but their charge wouldn't be affected at all. Clearly, we all still have something to learn about the pairing.�
Dec 28, 2014
Saghost I'm pretty sure that is the case - the car that plugged first gets whatever it wants, the second car gets whatever is left. I have no experience, of course, but that's what I've always read.
Assuming that is the case, it wouldn't have affected the girl at all, but Vger might have experienced some delays.

russman The other issue that I came across was knowing which of the 2 open spots had the most available juice and if it made sense to move from my slow spot to the spot that someone just pulled out of. I decided not to change spots, then someone else pulled in to the other spot and got a ton more juice then I did.�
Dec 28, 2014
bluetinc Not in the case when car 1 pulls in near empty, and then car 2 pulls in soon after. In that case car 1 wants to pull 120kW to charge, but car 2 will pull some of that reducing the charge on car 1.

tdiggity Harris ranch is the worst offender, followed by gilroy. People think they can take off and go eat for hours while their car charges.�
Dec 28, 2014
aronth5 Probably already mentioned in another thread but a software enhancement would help with a diagram of the stalls with the best charging rate and open highlighted in green and the other open stalls where paring would reduce the rate of charge highlighted in yellow. And stalls in use highlighted in red. This would alert the driver even before they pulled in which stall to use.�
Dec 28, 2014
SFOTurtle This is no doubt what happened on Friday, Boxing Day. I did a road trip down to Monterey and stopped at the Gilroy SC on the way back for a quick charge. All 10 spots taken. None of the drivers in sight. The outlet mall as a whole and In N Out were a total zoo. People were driving around in circles just to find parking spots. I've never seen it so crowded there. One MS pulled out after I waited for 5 minutes, and I grabbed the SC spot. When I came back to my car in 25 minutes not one MS had moved. I saw two MS just parked nearby not charging. I'm guessing that the majority of the folks were there shopping and probably were parked at the SCs for hours. The last time I stopped at Gilroy to use the SC was in August on a Friday afternoon, and I was the only car there.�

liuping Super Charging sure is different in Arizona.
We went from San Diego to Phoenix on the December 23rd, hitting Yuma and Gila Bend, with no one but us the whole time. On the 27th we went from Phoenix to Tucson, then that evening back home to San Diego. We hit Gasa Grande twice (on the way to Tucson and the way back to San Diego), Gila Bend, Yuma and El Centro. At every stop we were the only Tesla in sight the entire time. It was so strange compared to traveling in CA...�

Dec 28, 2014
bxr140 Hour? Yes. Hours? No... That place is tricky since there's really no other place to go but a full service restaurant. Some seats have a view of the SC slots, but not many.
I think what would be most helpful is a couple bullet point 'how to' sticker (heavy on etiquette) on the side of a SC pedestal, and possibly some more data and alerts from the mobile app...especially if the alerts can also identify capacity. Most people will read a sticker at least once, and most of them will probably try to adhere to the guidelines. There's never going to be full compliance, but it would be more helpful than a few enthusiasts complaining on some web forum. :wink:
Also, while probably not an actual reason for locating Swap there, its coincidentally convenient...�
Dec 28, 2014
bluetinc That may be true for a 135kW charger, I'm using all 90kW and 120kW chargers out here. These seem to like splitting off about 22kW/30kW to car 2 and work in discrete steps of divided power, rather than a perfect linear split as the two cars charge. Of course all of that depends on the health of the charger being 100%. I've been to quite a few that weren't at 100% so you get a double whammy.
�
Dec 28, 2014
FredTMC I can't believe how rude some owners can be. I never do this to fellow owners. The app helps too. You get a message that your car is done.
On a sidenote, it would be very easy for tesla to parse the supercharging files and look for repeat offenders that leave their cars at the stall after charging is done. Tesla should consider sending owners a gentle email reminder to have some courtesy for other owners. In other words, an owner's right to use superchargers doesn't include the right to block others from using them�
Dec 28, 2014
Saghost It almost certainly is discrete steps - the Supercharger is made up of a stack of several standard Model S charger modules, and I would assume that each module can only be hooked up to one output at a time (different voltage on each car,) so it would presumably shift in 10-11kW increments.
I hadn't realized that the older units would take some power away from the first car to guarantee some minimal charge rate on the second car. If that's the case, then if/when a car that can eat >135kW comes up, it may happen on the faster ones, too.
Walter�
Dec 28, 2014
Zarwin
+1 can confirm, was charging at about 110kw, second tesla plugged into my pair (there were no unpaired spots left) and the charge rate stayed at 110kw then tapered down as usual. If two cars pull into the same pair at the same time, the one that plugs in just after the other is getting a crap deal.
Edit: this was at a 120kw supercharger�
Dec 28, 2014
Saghost Maybe this is a spot where there's room for improvement. Perhaps using Tesla utilization data, they could set it up so that if all of the stalls are in use, the "your car is done" message has a higher level of notification (beep/vibrate) and includes a "and someone is waiting for the stall" piece. (Not sure if there's an existing way to know that there are cars waiting for certain.)
Walter�
Dec 28, 2014
liuping Why would you need a view of the SC slots?
I monitor the charging via the app and walk out and move the car when it done.�
Dec 28, 2014
tga This is just wild conjecture on my part, but I would expect they are switched in sets of three to keep the load on the 3 phases in balance.�
Dec 28, 2014
bxr140 A view makes it easier to monitor capacity. If you're pushing an hour for a meal but there are three stalls open, you can take your time getting out of there. If you're pushing an hour and there's another car waiting, go move your effing car. Who cares whether you're 'done' or not, an hour supercharging is more than enough for virtually every situation.�
Dec 28, 2014
David99 The majority of drivers don't know much about charging let alone Supercharging. They don't know how long it takes. Heck even Tesla doesn't know. That's why there is no estimate on how long your SC session will take (unlike on a L2 charger). The majority of drivers just plug in, they know it will take "a while" and they do something useful with their time. It's inconvenient enough having to stop and charge. Having to constantly check your phone to see how far your charge is while you are having dinner with your loved one is annoying and then having to run out and moving your car while the food on your plate gets cold is a major inconvenience. I totally understand that people don't want to do this. Frankly the time it takes to charge to get from SC to SC is just too long to sit in your car and wait, but also too short to actually go to a full service restaurant or do shopping or see a movie. The same is true for many public chargers. At Disneyland we usually spend 6-8 hours. Much more time than needed to charge my car. It takes about 18 min to go from the park back to the parking lot, another 5-15 min trying to find another spot in the busy parking lot, then another 18 min to get back to the park. No one does it, understandably.�
Dec 28, 2014
Saghost I'm thinking it doesn't really matter from the utility's standpoint. They want the three phases balanced, certainly, and the cabinet will have to try to address that as it activates/deactivates chargers when it isn't using all of them.
But I can't see that the utility will know or care if the SC cabinet has 11 charging one car and one charging the other, as long as they are all pulling the same AC current from the utility connection, which presumably would be the case if they are all providing the full output they can to the two cars.
Walter
- - - Updated - - -
There are variables in the process beyond the current and target state of charge, but all of them should be known and measurable at the time the session starts. I can't believe that Tesla couldn't provide a time estimate immediately after plugging in - assuming they knew the level you intend to charge to (I'm not sure how often people set and use the target charge level bars at Superchargers?) and assuming it won't steal power for the next car to plug in (which I'm learning in this thread the older units sometimes may?)
Walter�
Dec 28, 2014
Burt Court It's only going to get worser and worser as there are more and more Tesla's. I like the fact that more Superchargers are coming on stream, hope it keeps up with the demand.
I'm appalled and dismayed however that you would ever be so rude to take a cell phone into a restaurant (or a hospital or friends home). Whats the world coming too?
old geezer�
Dec 29, 2014
Cottonwood There has been a lot of discussion on this. There is no need to keep the 3-phase service in perfect balance, other users do not; Superchargers will naturally be close unless they try to create imbalance.
It would be great if someone that is second to plug in, does a careful observation to see how the rising charging power steps up.�

bluenation this is why tesla should never stop building SpC's..�
Dec 29, 2014
Saghost I'm pretty sure they're not planning to. Every car (except 60s without SpC) has a block of the purchase price set aside for the network - as they sell more cars, they get more cash to build SpC stalls with. It'll be interesting to see how they decide to balance expanding the network coverage, adding stalls to existing locations that are heavily used, and adding locations near the heavily used ones. There are advantages to each approach...

Dec 30, 2014
arnolddeleon I think I know who that "little girl" was assuming that was a gray Tesla. She was telling me about people not being aware of SC pairing and how someone pulled next them at Truckee while she was reading in the car. BTW she has her license (just recently) and has driven that Tesla. Her dad wanted her to take the Tesla for the driving test except it didn't have a front plate.
arnold�
Dec 31, 2014
mattreidy Maybe in the future, Tesla will need to monitor SC usage and when you leave your car plugged in for say beyond 15 minutes after charging is complete, they bill your credit card on file a penalty fee. Something significant enough that it would motivate most people to pay attention and move their car ASAP.�
Dec 31, 2014
HankLloydRight I'd go for that that, but only if Tesla could 100% insure that the Supercharger spots are *never* ICEd.
No way Tesla can charge OWNERS for taking a supercharger spot too long, and every other ICE driver can do it without consequences.�
Dec 31, 2014
Rheazombi Haha, good point. I wouldn't be able to handle the irony.�
Dec 31, 2014
aaron0k There is a new wave of MS owners out now. They don't troll owner forums or really care about pairing, etc. They bought the car for other reasons (status). I also wouldn't call them 'ignorant', they just want it to work... find a spot, plug in and move on. Expecting them to learn about paired stalls and amps is a lot of silly minutiae. TM could easily pop-up a window giving some basic info, however I expect they don't really want to... for other reasons (marketing).
SuperCharging is great concept to sell vehicles (removes range anxiety). However even die-hard Tesla superfans are starting to find it old and limiting; not practical for an expanding base (the type that wear A|X vs Tesla Logo jackets). I hope TM can focus more effort and resources on swap stations vs. superchargers; then we'll all be in a 'better place'.�
Dec 31, 2014
gaswalla went to San Juan Capistrano at 1030p on Monday: all stalls full.�
Dec 31, 2014
HankLloydRight I've said this before, but clearly the entire "pairing" numbering thing was designed and implemented by engineers. Stalls 1A,1B,2A,2B,3A,3B,4A,4B, etc is meaningless and confusing, even to those who know about pairing. First of all, the As and Bs are meaningless.. they are essentially identical stalls -- what differs is which one is plugged into first. Second of all, the numbers are also meaningless, other than telling which stalls are paired up. I've run into a few folks who knew about the pairing issue, but had it backwards -- that the "A" stalls are all paired banks, and if someone is already in an "A" stall, choose a an empty "B" stall. Ugh.
Anyway, if the entire thing had been designed by someone who knows anything about USER INTERFACES, each set of paired stalls would just have color stickers, say "Blue". So if you see someone already at a BLUE stall, pick one of the open RED, YELLOW, or GREEN stalls.
Instead of saying "All the numbered stalls are paired, so if you see someone at 1A, don't go to 1B, but rather one of the other NUMBERED pairs that's not occupied"... all you need to do to convey the entire concept is: "Choose a color where nobody else is already charging, unless all colors are occupied'.
Keep It Simple, Stupid.�
Dec 31, 2014
Saghost Agree that it could be simpler, but I think I'd take a different approach.
Put a prominent status light on each stall/cabinet (maybe sticking out of the top of the cabinet?) and give it a simple color coding.
Since the car uses Green for charging, keep that for one that's actively charging.
A stall that's degraded (either because the paired one is in use at high current or because of equipment failure) but available shows Amber.
A stall that's out of order entirely shows Red (or no light at all.)
A stall that's got full power and is ready shows Blue.
Still plugged in to a car but no longer charging could show Green, or Red, or no light at all, as Tesla chooses. (I'd lean towards no light or possibly Red.)
Pull in, look for a Blue light. If there aren't any, look for Amber. No thinking about what's in use and what's not, and the bonus of showing degraded and defective equipment as well as stall pairing.
Walter�
Dec 31, 2014
HankLloydRight Yeah, we've hashed through this before (I think in the Network thread), and that's a great system for future Supercharger design or upgrades. But that's an expensive proposition to retrofit the existing SC network.
What I'm suggesting can be done for $4 in color stickers for all existing Superchargers then next time a service technician visits.�
Dec 31, 2014
linkster HLR
Great idea! Even I can understand this solution. Should colored Tesla "T" stickers be centered above or below "T E S L A" or on the side (L or R) of each stall cabinet (with their permission of course)?
Btw, Good luck in getting the stickers to adhere to the stalls at Santee and Lumberton since some bored nutcase seems to have cleaned and waxed them this past Sunday morning.
�
Dec 31, 2014
Kipernicus This is a great idea. If someone just gets a message that their car is done charging, most of the time it the thought is "nice". But if the message was "your car is done charging and there are 2 others waiting in line" then people just might be a bit more inclined to interrupt/finish what they are doing and go move their car.
Follow-up messages should indicate how long their car has been sitting there not charging while others have been waiting.
I drove up the 101 on Sunday the 28th and when I pulled in to Atascadero there were 3 cars there. We had lunch at Denny's and when we were done eating there were 2 cars waiting. My car had not finished charging but we had enough to get to Gilroy and promptly left.�
Dec 31, 2014
scaesare You all aren't thinking grandly enough.
With auto-pilot/auto-park and the new metal snake charging cable connection, you drive to the front of the queue, give a voice command of "Robocharge!", get out of the car, and the S communicates with the mothership and determines status of the charging stalls, auto-drives to the one with the greatest current capacity, auto parks itself, and then plugs in.
When it's finished it then unplugs moves itself to a waiting area and signals you via the app, at which point you have the opportunity for it to come pick you up at the curb of whatever establishment you were patronizing (determined by the GPS coordinates in your phone and facial recognition, of course).�
Dec 31, 2014
Saghost Interesting. And plausible in the mid term, for Autopilot cars at least. I doubt that'll happen in the next few years, but it might be the standard pattern a decade from now. Valet parking and charging - but with no valets.
Walter�
Dec 31, 2014
HankLloydRight Anywhere where people standing or pulling into the SC area can clearly see the occupied stalls and the "color". So something near/at the top. Or just a 1" band that runs around the top, like a headband. In some SC locations, the numbers stalls are NOT next to each other, but interlaced, which makes it even more confusing at those locations. A simple color system would just work so much better across all SC locations.
Clearly, intelligent stalls that can just tell you which one is the best stall to charge is optimal, but in the short term, to explain to incoming MS/MX/M3 owners who might not get it, the 1A/2B system is really confusing.
That system must have designed by an MIT engineer. Scratch that.. if it were done by an MIT grad, it would have been: 0A,0B,1A,1B,2A,2B,3A,3B.�
Dec 31, 2014
bxr140 So out of curiosity, how much of a problem is pairing, really? The most I've experienced is 13 minutes of reduced charging. Annoying, yes, but it was also a full house so I didn't have any options anyway.
I think the only real negative out of it is the potential bad PR (regarding slow charging) from those not in the know, but its probably easy for enthusiasts to overstate that potential.�
Dec 31, 2014
HankLloydRight It's only a problem for people that don't know about it, and pull into a pair that's already charging at full throttle. Their charging is going to be very slow. If they pulled into an unoccupied pair, they'd also be charging at full throttle.
(pun intended)�
Dec 31, 2014
snellenr Color blindness (red-green or blue-yellow) afflicts 8 percent of males and 0.5 percent of females.
Numbers, letters, and additional education will be sufficient. A short hands-on session at a supercharger pedestal in the Service Center (even if it has limited power) at delivery time would be really, really useful to new drivers, and "here's what these letters & numbers mean" should be part of the training.�
Dec 31, 2014
roblab The problem is that it's easy to come up with suggestions for what the service tech could do, but this is something ANYONE could do, just like the "bored nutcase" that washed and waxed the Superchargers at one location. Why not? We have nothing else to do. I plan to buy a sheet each of blue, green, red and yellow and cut them into strips so the next time I'm at Harris I will be the bored nutcase putting up stripes on pairs.
I also plan to put up a simple sheet explaining pairing, printed black on white plastic sheet. How hard is this? Hopefully someone else beats me to this and it spreads to other chargers. One stripe on the leading edge where people will see it. Might cost me ten bucks. Compare this to charging a Leaf at WalMart.
I'd better buy a couple other colors for sites where there are more pairs. Black, obviously, and a light purple maybe.�
Dec 31, 2014
bxr140 Right, so why is it such a topic of conversation among those who do? Everyone on the webforums knows about it (or inevitably will after reading a few random topic posts...), so why the crusade? The problem only exists for those not 'in the know', and it only really becomes a problem for them if they actually understand and monitor charge rate AND they actually cares about charge time. Otherwise, ignorance is bliss.
Hell, the less people that know about SC pairing, the more likely the rest of us are to find an unoccupied pair!�
Dec 31, 2014
roblab OK, here's my notice, which would fit a standard 8.5 x 11 sheet. Any complaints???? "Speak now or forever hold your peace". I suppose Tesla could rip them off if they're offensive.
Or, I could just leave religiously oriented literature, hey??
SUPERCHARGER
PAIRING
1. Chargers are paired.
2. First car at a pair gets a higher charge rate which ramps down as battery fills.
3. Second gets lower rate of charge which ramps up as the first car ramps down.
4. For faster charging, new arrivals should seek to be the first car in a pair .

liuping A two light system would work for color blind people as well, with out having to add more expensive alphanumeric displays.
I just learned last week (when visiting a color blind relative), that there are smart phone apps now that can tell you the color of objects. Just point your phone at the object, and it tells you the color and color family. There are also apps the high lights adjusts colors that are not distinguishable to people with any of the color blind types.
- - - Updated - - -
This is a good start, but it only helps when there is an open unpaired spot available.
It would be helpful to know which cars are ramping down, so if we do need to pick a paired charger, we pick the best one.
Only Telsa can do it properly.
I think the best solution is an in car screen that pops up when you arrive at a supercharger site, with a layout of the chargers, and a indicator of the best one(s) to pull into. No retrofitting the Hardware at the SuperChargers, just a software update for the cars.�
Dec 31, 2014
Lloyd And a side effect of taking Viagra!! :scared:�
Dec 31, 2014
bxr140 Yes. If you're going to go through the trouble of grassroots education, explain more than just pairing. Explain the taper, explain the un-coolness of topping off while others wait, etc. Otherwise, your note doesn't actually solve any problems.
Other random thoughts, specifically on the 'splaining of pairing:
--We take for granted that pairing means electrical equipment is shared. It may be helpful to make that connection for someone not in the know.
--#2 bullet is irrelevant and confusing as it can imply car #2 has some affect on car #1.
--You'll need 1000 words of the paired chargers for each location you tag�
Dec 31, 2014
markb1 All these ideas are over-complicated. The best user interface would be to not expose us to the concept of pairing at all. If they really wanted to make sure the charge rate is prioritized by order of arrival, then the solution is to design the system such that charging pedestals can be automatically switched between superchargers. An even simpler solution (and the best one, IMO) is to just let everyone be ignorant of pairing.
I'm actually happy with the way it is right now. I understand the numbering scheme, and I don't think I'm much affected by people who don't. It seems there is only the potential for small penalty if you are the first to plug in. The system mostly penalizes those who don't understand the numbering scheme, but even that penalty is mild.�
Dec 31, 2014
HankLloydRight The incidence of color blindness is minuscule compared to the incidence of stupidity/ignorance that is going to happen when more of the "masses" get access to Tesla vehicles.
If a color system helps solve the pairing problem, that incidentally 8% of the population can not use, that's 92% of the population that is helped by it. And for the 8% who are color blind? Well, that's not any better than the confusing system we have now (we can leave the letters/numbers on the stalls... they don't need to be removed.)
I disagree. There's a reason that simple, intuitive, user interfaces exist. They don't require "education." Meaningless numbers and letters are not intuitive at all, and cause confusion. The person I ran into at the SC location *was* "educated" on how pairing works at the service center upon delivery, and he *still* got it backwards and thought all the "A chargers were on one shared bank, and all the "B" chargers on a second shared bank.
It would be very hard to confuse a simple color system that simply says "don't charge with a pair color already charging" or "pick an empty color pair if available'. No numbers, letters, banks, confusion, tapering, etc. Just pick a color. No "education" needed.�
Dec 31, 2014
liuping If 8% of the male population was prior to Viagra, the number is going to climb.
Why implement a system you know will fail for 8.5% or more of your customers, when there are alternatives that will work for everyone?
Why not just have a single light on each pedestal, and turn it on when it's a "good" charger to use. If there are 8 stalls, initially only 4 lights would be on (one from each pair). When one charger from each pair is filled, light the paired stall with the most power available, etc.. The rule for the drivers is simple: pick any stall with the light on, and everyone is guaranteed to get the fastest possible charge.�
Dec 31, 2014
HankLloydRight As I said above, yes, an intelligent charging stall is optimal. But that's not the priority for Tesla to retrofit 300 SC stations with new electronics, hardware, and software.
Stickers, OTOH, cost $4.
As I said, we've been through all this before. I'm not saying one system is better or worse, but in terms of bang for the buck and simplicity? Yes, I could sit here and architect the perfect SC charging stall notification system that integrates all of the above, as well as approaching cars, their charge status, their destination, yadda, yadda, yadda... it would be enormously complex and beneficial. That would be cool.
But again, I'm talking about $4 stickers.�
Dec 31, 2014
liuping I guess I don't see the problem with the current labeling system: 1A/1B are paired, 2A/2B are paired, etc. How is that not clear to people that know about pairing?
The problem is that many people don't know about the pairing at all, so any sign explaining it should help.
I wish Tesla would at least mention it to the customers during the delivery process.�
Dec 31, 2014
FredTMC i agree. I know how pairing works. Many don't. Doesn't really impact me much.�
Dec 31, 2014
Trnsl8r Best idea on TMC I've heard all year.�
Dec 31, 2014
roblab This is great input. But let's get real. Tesla is trying to make new Supercharger stations at an amazing rate. They are NOT going to go back and figure out a system of lights. If they take time to make little lights, there will reallllllly be a backlog at SC stations. Which, by the way, I have not experienced yet. Same with making software for sending messages to all cars in a geolocation. They are busy making software which will drive your car.
Granted, there are those who don't care. Conversely, there are those who do, who want to know. I might try to make my simple instructions simpler, but that's the key word: KISS. And probably very few will care, notice, or care, or notice. But I think I will do it anyway. I bet it will beat the installation of little lights by a few years. Could be wrong.�

HankLloydRight Because even people who know about pairing *still* get it wrong.
Just because people here get and understand the current system doesn't make it a good system.
I'm sure many people understood Windows ME, The Edsel, and New Coke... That doesn't make them good products.�

markb1 I don't think Tesla ever intended for us to care about pairing. It doesn't matter that much, and I'm pretty sure Tesla intends for us to ignore the numbers and plug in wherever we want.�

dandelot I know about pairing and yet still have not found the IDs on the SC stalls, so I just
sort of stayed away from other folks charging.�

cpa The more recent Superchargers have the "TESLA" wording across the top lighted in red. It would be easy on future installations to color-code the "Tesla" logo for availability. It might be more difficult in bright sunlight, but at least when a driver pulls up, he/she could see the potential of the stall chosen. All green means maximum rate. All red means minimum rate. A mixture would indicate sharing is in effect with a paired stall, so a green "T" would be charging at 20%, a green "TE" at 40%, etc. I think this keeps thing simple and easy to understand. This would be an easy retrofit to the existing Superchargers as well.�

bonaire Pairing is important but does not show up clearly to newcomers on the web site. If you were doing your first trip, using SC recharging, and all sites had busy, almost full stalls, you end up with shared pairing recharging and far more charging time than expected from the outset. Simple enough to advertise 120Kw or 135Kw recharging. But those numbers have a few details and an asterisk with rules below should be taught to prospective buyers to educate during the research and sales process. I also said almost full. This thread also says that wait queues are happening and that is before you jump onto a paired stall and get a lower charge rate than expected until your paired partner pulls away or finishes charging.�

liuping They are not making any software to drive my car. Maybe my next one.�

markb1 But how much does it really affect charging time? If you are second to plug in, you might have to wait until the other car tapers before your charging rate picks up. But that shouldn't be very long.�

ljwobker Random data point for anyone who actually cares.... I drove my 85 across the country from Raleigh NC to Palo Alto, and until I crossed the NV/CA state line, we saw roughly 10 other Model S cars *combined* at all supercharging stations. Then I arrived in California and there were cars everywhere. We didn't have to actually wait in line at any point, but at Gilroy, Atascadero, and Tejon Ranch there was nearly 100% occupancy.�

pilotSteve numbers, letters (1A,2A). When there is a 50/50 chance of getting it right, the odds you are wrong is 100% :crying:�

David99 If the first car is near empty and then you plug in as a second, you only get about 10-20 kW. The first car will not start to reduce the current until about 15-20 minutes later. So for the first 15-20 min you are only getting maybe 20-25 miles charged. Then the first car starts to reduce charge power and the second one slowly gets more and more. The first car will always get as much as it can handle and the remainder goes to the second car. So if you plug in as a second car shortly after an empty car started charging, you will easily double your charge time. Of course that's worst case. In reality it rarely happened to me that I had my charge time doubled. For the most part I get a free pair and charge as fast as it's possible.�

jdevo2004 Letting people charge on the honesty system will never work. Tesla is going to have to figure out a way to make people move their car when it is finished charging.�

TTT So you made it from San Diego to Yuma on one charge? I drove down to El Centro from San Diego with only about 80 rated miles

This would be a great software upgrade feature�

stevezzzz I understand pairing perfectly well, and yet I have pulled into precisely the wrong stall, and I've done it more than once. That's the sign of a bad user interface.�
Jan 6, 2015
David99 Same here. Often it's hard to see it at night when you drive up. At some SC they are next to each other, on others all As are next to each other, then all Bs which makes things worse.�

apacheguy Yeah, this just goes to show the US market for Tesla's - it really is overly concentrated in CA. And yet Germany has more superchargers and much, much, much fewer cars. Sorry, I don't agree with that strategy.�

Jacina Because for people like me who actually travel in Europe, having a SC network is a prerequisite for buying? Any vacation I take with the car would require these.
If there weren't such a nice network in Germany I'd not even consider a Tesla. There's only 1 supercharger around Thun/Interlaken missing for me, then I'm set, I hear thats being worked on so good�

RiverBrick Germany is a crossroad, so you can't just go by resident cars. Currently, there are precisely zero Superchargers in my province for nearly 400 Model S, but if Norwegians had to drive through on business or on vacation, there'd be 20 sites up and running.�

Rheazombi IMO, nagging non-savvy Tesla drivers will only backfire. The only real solution will either be some kind of sophisticated automation (maybe involving the solid snake arm), or just building more stalls.
Education can help tho. People already subconsciously seem to know not to park in front of the gas pump while they go take a number 2, and they don't have nagging txts showing up on their phone telling them they've left their vehicle for too long.�

bevguy Crowded Superchargers? In most of mid America we should be so lucky. Our problem is no superchargers. I live in a 1 million plus metro area, the only SC within 200 miles is to the East. Any other direction it is way more than that.
Tesla has concentrated on California and the EU and left the rest of us Tesla owners to wait, And wait..�

ecarfan Look at the latest 2015 and 2016 Supercharger maps on the Tesla website. Your time is coming. Tesla can only build them so fast. They started just 1 1/2 years ago and have made amazing progress. That progress is continuing.�
